LASTINGMACHINE.

SPECIFICATION forming part of Letters Patent N o. 893,760, dated.December 4, 1888. Application filed January 27, 1888. Serial No.262,148. (No model.)

To all whom it may concern:

Be it known that we, RUSSELL HATHAWAY and ELBRIDGE G. PAULL, ofFairhaven, county of Bristol, and State of Massachusetts, have inventedan Improvement in Lasting-Machines, of which the following description,in

I connection with the accompanying drawings,

is a specification, like letters on the drawings representing likeparts.

This invention relates to that class of lasting-machines which isadapted to lay the edge of the upper over upon the inner sole or bottomof the last through the action of a shirring cord, thong, or wireconnected with the edge of the upper, the said cord, thong,l or wirebeing drawn upon and acting as a puckering or shirring device to gatherthe upper into a smaller space. The shirring cord, thong, or wire ispreferably connected with the upper through a pocket or channel, and, asherein shown, the said pocket or channel consists of a series of loopsof thread pushed through from the inner side of the upper outward ashort distance from its edge; but instead of the particular shirringcord, thong, or wire herein shown we may employ any other well-known orequivalent cord, thong, or wire, as, for instance, in United StatesPatent No. 248,566, dated October 25, 1881.

The machine herein to be described contains a toe-rest and heel-pinadjustable one with relation to the other to constitute a jack by whichto hold the last and shoe-upper thereon firmly in position while thecord, thong, or wire is .being drawn, as described, to lay the edges ofthe upper over upon the inner sole or last bottom. The cord, thong, orwire is engaged near the toe and at two or more points between the ballof the foot and t-he heel by hooks or draw-bars attached by ieXibleconnections to the ends of arms or levers set in motion by rock-shaftsunder the control of suitable levers to be movedby the hand or by foot,each of the said levers having co-operating with them suitable means bywhich to retain them in the positions in which they may be left bytheoperator.

Our invention consists, essentially, in the combination, with a jack tohold the shoe and arms or levers and means to move them, of

hooks or draw-bars and intermediate connections between the said hooksor draw-bars and the said arms, whereby by turning the said rock-shaftsor the said arms or levers the said hooks or draw-bars will be made topull upon anddraw the said cords, thongs, or wires in such manner as tolay the edges of the upper snugly over upon the inner sole or bottom ofthe last.

heel-pin.

The bed-plate A, supported upon suitable legs, A joined together bycross-bars A2 and a cross-rod, A3, has at its ends suitable bearings forlike rock-shafts, A4.

Each rock-shaft A4 has attached to it a lever, B, (herein shown asprovidedwith ahandle, B,) each handle having a suitable projection, asa, to engage the teeth of a rack, d', the said projection and rackforming a locking device for the lever to retain it in the position inwhich it is left by the operator.

Each rock-shaft A4 has fast upon it two hubs, O, provided with uprightarms C', each arm having upon ita clamp, as b, which is held in positionby a set-screw, b. Each rockshaft A4 has also mounted upon it loosely ahub, D, which is connected with a projection, D', of a lever, D2,loosely fulcrumed upon the said rock-shaft.

The inner ends of the like .lever having its fulcruin upon the rod A3,

the said levers D2 being normally acted upon by spiral springs D4,connected therewith and with the cross-girt A2, the said springs actingnormally to keep the front end of the lever or treadle D8 elevated, asshown in Fig. 3.

Each hub D has rising from it an IOO arm d. 'l`he arms t" and d haveattached to thcm like clamps I). llaeh clamp in connection with the saidarm holds the inner end of a flexible connection, d2 or di', theopposite end oi' which has attached to it a draw-bar or hook, d" or di',the said connections, as herein shown` having cti-operating with themspiral springs, as rl, which act normally to shorten the ei't'ectivelength ot the said connections,

so that when the operator grasps a hook or` draw-bar and passes itacross the shoe and eng.1ges it with the d raw-cord, thong, or wire t atthe opposite side ol' the shoe and then releases the hook or draw-barthe said spring assumes control ot' the connection and hook or drawbarand maintains it in engagement with the said cord, thong, or wire.

ln practice the hooks or dra\\'bars may be engaged with thetireur-cords, thongs, or wire. as t, at ditierent places with relationto the length oi` the shoe, as shown in Fig. l, and the shoe having beenproperly jacked, as will be described,the operator will preferably tirstput his li'oot upon the treadle l)R and operate the two arms d to causethe hooks or drawbars d* to draw the cord, thong, or wire in and aboutthe toe of the upper, so as to lay the edge of the upper snugly overupon the inner sole, c, laid upon the bottom of the last e', the treadleD8 when depressed heilig retained in its depressed position through theagency of the locking-bar c?, having' a series ot' notches e", whichengage the edge otl a plate, e", herein vto be moved shown as attachedto the bed-plate A byI usual or suitable way move the levers l3,turn-`f", attached to the screw-threfuled shank j ing the rockshatts A", andwith them the arms C', thus, through the connections d3, pulling thehooks or draw-bars d5, so that they then, tu engagement with thedraw-cord, thong, or

wire t, will draw the upper about the last and over upon the. inner solethereon along the ball ot the t'oot and into the shank and more or lessabout the heel, as necessity may require.

v ln practice there may be as many arms C as may be desired, thatdepending upon the length ot the shoe and the class ot work to be donc.

The bed-plate A has mounted upon it an inclined track,f, provided at itsupper end with a series ot' notches, the said track receiving upon itthe lower end of a carriage,

j", having at its upper end a toe-rest, f2,

which maybe padded in any usual manner.

'lhe lower end ot` the carriage is slotted to embrace the track, and inthe slot there is a project ion,(see lfig. l,) which may enter in one otthe notches and retain the carriage in position upon the inclined track.The bed-plate has at its lower side a hollow hub, g, in which is placeda rod, g', to the upper end of which is pivoted at g? the heel-pin 71,the lower end of the heel-pin (shown separately in Fig. t) being beveledor inclined to be acted upon by the upper end ol' a loose ring, l1',which rests upon the upper end ot' a nut, lf2, made adjustable upon athreaded sleeve, Il, secured to the bed-plate above the hub o, butsurrounding the rod g.

In practice the upper, having' the. draw cord, thong, or wireinmwporatcd with ity near its edges, so as to be drawn upon bythe hooksor draw-bars, as described, is placed upon a suitable last, as e', andan inner sole, c, is laid upon the same, and the last. is then placedupon the heel-pin in usual manner, the forward part ol' the last or itstop portion resting' upon the toe-rest, substantially as indi cated bydotted lines in Fig. il. ln this condition the nut /11' will be rotated,thus elevating the loose collar/1', and the latter as it rises will act,upon the inclined end /i ot the heel-pin 71 and will cause the upper endol' the said heel-pin, in engagement with the last, l'orward toward thetoe-rest, forcingI the top ol' the last near its toe Iirmly down uponthe toe-rest. 'lhc rotation of the nut is continued until the heelpinhas been thrown t'orward to thoroughiy conline or lock the last inposition upon the jack composed 'ot the said heel-pin, its adjust ingdevices, and the toe-rest, and alter this the hooks or drawhars will beengaged with the cord, thong, or wire to draw the same in the mannerbefore described.

'lfhe toe-rest carriage will be adjusted horizontally according to thelength of the last, and in its adjustments will be raised or lowered,owingI to the slope given to the inclined track j", thus adapt i ng thetoe-rest to the curvature ot' the top ot' the last. l`he inclined trackf is held in place by means ot" a nut,

thereol".

ll'aving described our invention, we wish it. to be understood that wedo not. desire to limit; our invention to the exact lorm oi' hooks ordraw-bars and connections between them and the arms for actutuing them,nor do wc desire to limit our invention to the exact. shape or lornl ofthe levers employed for actuating the rock-shafts A", or to thc sprinfor keeping the hooks in engagement with the cord t.

We do not herein claim nippers to engage the material of the upper, thesaid nippers being' attached by flexible connections to levers, by whichthe upper is drawn over upon the inner sole; but in our invention thehooks or draw-bars in all instances will be so constructed as to engagethe shir cord, thong, or wire, the strain put upon thc upper to lit itupon the last and to draw its edge over upon the inner sole being' donethrough the said cord t.

l. In a lasting-machine, a jack containing an adjustable heel-pin andlongitudinallymovable toc-rest; to hold the last and upper thereonfirmly, combined with one or more arms or levers, as C', at each sidethe jack, rock-shafts to which the arms are attached,

lOO

means to operate them, and one or more hooks or draw-bars andconnections between them and the said arms, to operate substantially asdescribed.

2. In a lasting-machine, a jack consisting of a heel-pin and toe-rest,two arms, d', levers D2, operatively connected therewith, and a lever ortreadle to actuate the said levers D2, combined with hooks or draw-bars,as d, and intermediate connections between them and the said arms d2, tooperate substantially as described.

3. In combination, a jack containing` aheel.- pin and a toe-rest, tworock-shafts having' connected arms g', connecting devices and hooks ordraw-bars, as d5, attached thereto, arms d', levers and treadle to movethem, hooks or draw-bars, as dfi, and intermediate connections betweenthem vand the arms d', combined with means to actuate the saidrock-shafts independently of the levers D2, substantially as described.

t. In a lasting-machine, a jack to support the last and upper thereon, aseries ort' hooks or draw-bars arranged at each side ot the last, armsVC and d', and iiexible connections to attach the said hooks ondraw-barSto the said arms, combined with means to actuate thc arms dindependently ot' the arms C', as and for the purposes set forth.

5. In a lastinganachine, the pivoted hecl pin, the loose collar, and nutto turn the said heel-pin upon its fnlcrunn combined with the inclinedtrack and with the toe-rest carriage adj ustably mounted thereon,substantially as A described.

6. In a lasting-machine, a jack, a heel-pin and toe-rest, and an arm, asC', combined with adapted to hook into or engage a cord or thon gloosely connected with the edge of the upper, a series of arms and meansto actuate them, and flexible connections between the arms and the saidhooks or draw-bars, combined with springs adjacent to said flexibleconnections to normally cause the said hooks or draw-bars to remain inengagement with the said cord or thong` after the operator has engagedthe said hooks or draw-bars there- 1with by hand,substantially asdescribed.

9. In.' a lasting-mac]line, a series of levers or arms and hooks ordraw-bars and flexible connections, combined with longitudinallyadjnstablc loops or slides mounted on the said levers or arms and to whichone end of the said connections is attached, substantially as described.
